Colts interim coach Bruce Arians should be somebody’s head coach next season.

The job Arians has done with the Colts is hard to overstate. Playoffs? Playoffs? Yes, the Colts can lock up a playoff berth Sunday by beating the Texans, and Arians‚ performance as interim coach should be enough to convince an NFL owner to hire him.

Arians knows quarterbacks, working for years with Ben Roethlisberger in Pittsburgh, and now with Andrew Luck. Arians knows how to handle adversity, showing an admirable mix of compassion and leadership after Colts coach Chuck Pagano was diagnosed with leukemia.

We’ll find out if the Colts are ready to win a huge December road game in Houston. But we already know Arians is ready.

The Ravens‚ decision to can Cam Cameron made sense.

The slumping Ravens (9-4) have a tough schedule to end the season—Broncos on Sunday, Giants in Week 16, at Bengals in Week 17. That factored into the decision to oust Cameron as offensive coordinator. Their offense has been inconsistent, with Von Miller and the Broncos' imposing pass rush arriving in Baltimore on Sunday. The Ravens can’t fake their way into the postseason and beyond. Ray Rice, their best offensive player, can’t afford to go long stretches without touches. Joe Flacco has to play better, especially if he wants the Ravens to utilize more no huddle.

History suggests Jim Caldwell can handle this role. Don’t knock him because he hasn’t called plays since he coached at Wake Forest. Caldwell spent years with the Colts, working on game plans with Peyton Manning and offensive coordinator Tom Moore. Caldwell has been a head coach in the NFL on a team that went to the Super Bowl. That experience will help Caldwell, because this is not an easy situation, taking over as offensive coordinator with three games left. But if the Ravens were going to make a move, coach John Harbaugh obviously felt this move had to be made.

If the Texans are carved up by Luck on Sunday, Houston has a problem.

Luck and Drew Brees lead the league with 18 interceptions. Thirteen of Luck’s 18 picks have come on the road.

Despite Luck’s impressive rookie season, he has had issues with turnovers on the road. The Texans host the Colts on Sunday, and if Houston loses, the Colts will have a chance to steal away the AFC South title.

Two elite quarterbacks have already lit up the Texans in their two losses—Aaron Rodgers and Tom Brady. If Luck comes into Houston and torches the Texans, it raises more doubt about the Texans' defense being Super Bowl ready.

A lot of NFC teams will be rooting for the Browns to knock off the Redskins.

Whether or not Robert Griffin III plays, the Redskins (7-6) can’t afford to lose in Cleveland on Sunday. Having won four straight, the Redskins have morphed from a team that looked in disarray into a dangerous team. Nobody in the NFC wants to deal with trying to stop Griffin in the playoffs. If the Browns knock off the Redskins and hurt their playoff chances, a lot of teams in the NFC will say, “Thank you.”

The Falcons (11-2) are no longer flying high and need a statement against the Giants.

Nothing is coming as easily for the Falcons as it did earlier in the season. Beating the Giants on Sunday won’t be easy, either.

Think about this. If the Giants win Sunday, they’ll have victories this season over the 49ers, Packers and Falcons. The Giants don’t fear anyone in the NFC. But strange as it sounds, the team that might make the Giants most nervous in playoff matchup? The Redskins.

The 49ers need a lift from special teams Sunday night.

Andy Lee of the 49ers may be the league’s best punter. His role in the 49ers' success is sometimes overlooked. The 49ers' best chance to slow Tom Brady and company is by winning the field-position battle and forcing the Patriots to execute long drives. That will be one of the great matchups Sunday night—the 49ers' physical defense against the Patriots' precision offense. I like the Patriots in this game, but Lee and the 49ers' special teams edge will make Brady’s job harder.

If the Cowboys win Sunday, we have to look at them differently.

Tony Romo and the Cowboys have taken plenty of heat for fading in December. But this Cowboys team is showing resiliency heading into Sunday’s crucial home game against the Steelers.

Last Sunday’s come-from-behind victory over the Bengals came under nightmarish circumstances—the day after Jerry Brown of the Cowboys was killed in a car accident, and teammate Josh Brent was arrested for intoxication manslaughter. The Cowboys are 2-0 in December, and Dez Bryant has decided to delay finger surgery to play. If the Cowboys (7-6) make the playoffs after all they’ve been through, they’ll deserve a tip of the hat.
